Matsya Purana — Catalogue of the Eighteen Puranas
पञ्चाङ्गानि पुराणेषु आख्यानकमिति स्मृतम् सर्गश्च प्रतिसर्गश्च वंशो मन्वन्तराणि च वंश्यानुचरितं चैव पुराणं पञ्चलक्षणम् //
pañcāṅgāni purāṇeṣu ākhyānakamiti smṛtam sargaśca pratisargaśca vaṃśo manvantarāṇi ca vaṃśyānucaritaṃ caiva purāṇaṃ pañcalakṣaṇam //
It is taught that the Purāṇas have five limbs: ākhyāna (narrative), sarga (creation), pratisarga (re-creation), vaṃśa (genealogies), manvantara (the cycles of Manus), and vaṃśyānucarita (the histories of dynasties and their successors). Thus a Purāṇa is marked by these five characteristics.
It frames cosmic history through sarga (creation) and pratisarga (re-creation after dissolution), indicating that Purāṇas systematically describe recurring cycles of manifestation following pralaya-like resets.
By highlighting vaṃśa and vaṃśyānucarita (dynastic lineages and royal chronicles), it supports the Purāṇic model where righteous kingship, succession, and exemplary conduct are preserved as ethical templates for rulers and householders.
No direct vāstu or ritual procedure is stated; the verse is a classificatory rule—useful for cataloging Matsya Purana content, including later sections where temple architecture and rites appear as part of the broader Purāṇic narrative framework.
